i'm into hit and miss engines as well as cars. i am amazed how many survived ww11..
A Manchester NH friend is now 80 years old and starting to "dissolve" his collection.
The "name brand" engines particularly those of New England manufacture go for seriously big bucks. Completeness is paramount, but its surprising how much can be gone and still retain a "market value."
Other more common engines if operable are worth considerably less. Think "inflation adjusted original cost." A Kenwood (Sears Roebuck brand) engine originally sold for about $24 in a 1920s era catalog. Google query $24 in 1924 =
$411.74 in 2023.
And my friend just cleaned out an entire bay to an antique purveyor - like 15 unrestored and even questionable completeness engines for about $2800.
The problem is those who "grew up" using and knowing these engines are passing - their attention is "waning" - and the new generation doesn't have the connection.
The Model A may be unique since in the pre-war years it occupied the position of "car available." The improvements in "modern" cars quickly obsoleted earlier less "functional" cars. Think today about a screw-in fluorescent bulb - worth more as pulverized dust than as a light source.
Dad on the eve of WWII bought a 1929 Model A RPU from the junkman for $15. Drove it while at home from college for three years. Sold it back to the junkman in 1943 for $15.
"Best deal on a car I ever got" he said.
$15 in 1943 =
$263.42 in 2023.
I.e. about 1cents a pound then and today. Scrap value.
One imagines with wartime steel production being what it was, that car didn't last long as a car.
